it The invention refers to a yarn pack with the thread or yarn disposed in layers in back and forth arrangement, and separating sheets provided between the individual layers, as well as to a method of and means for preparing such thread packs.

In a known design of this type, the thread of each layer is in zig-zag or serpentine fashion. Byreason of the manufacturing method of this type of construction with the aid of two series of pins around which the thread is slung back and forth, the two parts of the thread of a back and forth length are disposed apart from one another by at least the diameter of the pins employed. By reason of this, a, comparatively large space is required for coiling thread of a definite length and from this results an excessive consumption of paper and the like for the thread pack andrather elevated cost in preparing the pack.

Spooling is comparatively difiicult, time consuming and expensive. In addition, the thread is subjected to comparatively heavy strains through the forces active inthe oscillating thread guiding mechanism. To maintain the thread pack incompact order causes certain difliculties, especially in the case of-larger numbers of layers. To avoid these shortcomings, the' individual layers of -threads,- in accordance with the invention,are madeup of flat longitudinalheliccidal windings disposed one above the other in more or less it scale-like manner. mln this way, volume] required is reduced considerably, it being a fraction only of what is neededwith the known arrangement, While; with the known arrangement, the rectangularly'shaped separating leaves or strips are provided-with a slit passage for thethread to pass on' -to the next following layer, the last portion of the thread of a layer, in accordance with the invention, contained within the frameshaped separatingleaf supporting the same, is passed on to the next following layer disposed thereto in crossed relation.

..The..separating leaves in the form of double strips are fastened with their endsto the strips ofthe preceding layer disposed crosswise thereto, or to the base plate, respectively, or glued thereto. i Onthe outside of the thread returns, distance strips have been provided corresponding in thicknessizto the thickness of the compressed thread layers; In this manner. the totalthread thickness of the thread layers is equalized, in such awaywthat the packat its'glued corners will not 13 Claims. (01. 206-64) present a reduced height but will rather form a uniform cube or a rectangular prism, in such a way, that any number of thread layers may be piled one above the other. i

In accordance with the present invention, the method of preparing the novel thread pack consists in that each layer is formed by coiling the thread in helical fashion on a coiling mandrel of rectangular shape in longitudinal section, stripping the coil off and pressing the same flat simultaneously, in such a way,- that the thread portion and the windings are in close contact and the coils are more or less superimposed in scale-like manner. Further characteristics will become evident from the claims in connection with the following description.

The drawings show executions of the invention by way of example,

Figs. 8 and 9 give views from above and laterally of another type of execution of the pack; and

Figs. 10 and 11 are perspective views of the pack with open lid.

In order to give the yarn thread the shape of longitudinal helicoidal windings, thread I, according to Fig. 1 is wound in a helicoidal line around a leaf-shaped coiling mandrel 2 or on correspondingly disposed tongs or bolts. In this manner, helicoidal windings with long paralielly extending lateral parts and rounded ends I are developed. The coil is then stripped off the mandrel and simultaneously compressed or pressed flat insuch a way that the posture of the thread 3 of the coil such as shown in Fig. 2 is developed in which the individual helicoidal windings are superimposing one another in scale-like fashion.

In doing so, the distance between the two thread parts of a winding may be selected in such a way that the reciprocal superposition of the helicoidal windings may be of larger or smaller extent. In an extreme case, the two thread parts of a helicoidal winding may extend in an identical plane in close relation to one another.

On the layer of thread 3 considered here, an additional layer of thread 4 (Fig. 2) is placed which, however; extendswertically or at'any other desired "angle a's- "regards the direction of lthe thread relative to thread layer 3. Additional thread layers follow above in such a way that each layer of thread is displaced..by.90.-degrees with regard to the layer of threadnextibelow.

Between the individual layers of thread'framelike separating leaves 5 are disposed'iin the. man-1. ner illustrated in Fig. 3. The central part or the thread layers is freely displayed .withi-n gap 5 of.

pressure under which the thread turns are held together 1 is..calculated suc'h ath'at-it will .not change thee-structure of thethread with any detrim'ental effect. This pressure :isex-erted by theithin freely extending edge of separating leaf- 8.

"Separating. frame- 5' isv preferentially.formed :by separating Strips-L8 (Fig. 5). :of which twolonly are requiredior' each layer 1 of thread. in .sucha way, that.by layersa vertically and a horizontally disposed'pair-of separating stripsS will-be utilized.

By the. layer-wise, alternating positioning of a double 4 strip '8, 19' each lengthwise and" crosswise, and the union of the corner portions. a skeleton ltofthe'forin shown in Fig. 6 is'developed.

The individual helicoida'l windings are disposed within the thread layers in such a way that by withdrawing the thread in the direction of arrow l3 (Fig. 2), the helicoidal winding happening to be uppermost oi the thread layer is taken oil while the ones followin below are being detained at the thread returns.

The finished thread pack which at the bottom 'is'gprovided with a closed base plate M (Fig. 4) is provided. at the .top preferentially with a wholly :orpartlytransparent covering plate 15 (Fig. 7)

which, in its center, has a hole l6 through which threadd lispassedatoward the outside.
